Δpqr is dilated from the origin at a scale factor of one half to create δp′q′r′.
select the option that completes the statement:
the triangles are because their corresponding sides are and their corresponding angles are
a. congruent; similar; proportional
b. congruent; proportional; similar
c. similar; congruent; proportional
d. similar; proportional; congruent

  D. similar; proportional; congruent

Step-by-step explanation:

Any pair of figures is similar if their corresponding sides are proportional and their corresponding angles are congruent. That is the meaning of similarity.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

b
